GNU cpio copies files into or out of a cpio or tar archive.
The archive can be another file on the disk, a magnetic tape, or a pipe.
(See also the included mt program. rmt is not included
to avoid conflicts with the version from fw_tar).

GNU cpio supports the following archive formats: binary, old ASCII,
new ASCII, crc, HPUX binary, HPUX old ASCII, old tar, and POSIX.1 tar.
The tar format is provided for compatability with the tar program.
By default, cpio creates binary format archives, for compatibility with
older cpio programs. When extracting from archives, cpio automatically
recognizes which kind of archive it is reading and can read archives
created on machines with a different byte-order.
